Patek Philippe rarely makes watches in stainless steel, outside of its sportier Nautlius and Aquanaut collections, so the new Annual Calendar, which contains the automatic caliber CH 28-520 IRM QA 24, will strike many Patek aficionados as something of a surprise. The masculine dial conveys a sense of depth with its applied hour markers, applied blackened-gold frames for the calendar windows (day, date, and month), and blackened appliqués for the chronograph scale and 12-hour scale.
Black is also used for the faceted hour and minute hands (which are coated with Super-LumiNova), the 12-hour counter hand, and the power-reserve hand, and a bright signal red distinguishes the central chronograph seconds hand and the hand for the 60-minute counter. The model’s “monocounter” subdial has been reconfigured, with the 12-hour counter scale on the outside and the 0-to-30-minute and 30-to-60-minute scales in the middle and inside, respectively. Caliber CH 28-520 IRM QA 24, which is equipped with column wheel and disk clutch, also powers a day/night indicator at 6 o’clock. The Patek Philippe Annual Calendar Chronograph Ref. 5960/1A has a stainless steel bracelet with droplet-shaped links and a stainless steel fold-over clasp. The price is from USD54,000.
